Gelesis® Reports Fiscal Year 2021 Results and Fiscal Year 2022 Financial Outlook

The Company ended the year with 79,100 total members for Plenity®, demonstrating strong demand ahead of first quarter 2022 debut media campaign

Gelesis reaffirms guidance for $58 million in product revenue and anticipates 400% growth in 2022 following strong early launch results reported earlier this month, including record-high levels of prescriptions and online traffic

BOSTON, MARCH 24, 2022 – Gelesis (NYSE: GLS), the maker of Plenity for weight management, today reported financial results for its fiscal year ended December 31, 2021.

Yishai Zohar, Founder and CEO of Gelesis, commented, “Earlier this year, we kicked off our debut media campaign for Plenity and have already seen 3.5-fold growth in new Plenity prescriptions in the first few weeks since we began advertising. Demand through both our telehealth and our traditional healthcare provider channels has quickly reached record highs. We are thrilled by the feedback we are receiving from thousands of new members who have recently begun their weight loss journey with Plenity.”

As previously reported, Gelesis raised $105 million in gross proceeds upon completion of a business combination with Capstar Special Purpose Acquisition Corp. on January 13, 2022, debuting the following day as a publicly traded company on the New York Stock Exchange under the ticker symbol “GLS.” Gelesis CFO Elliot Maltz said, “We began investing in broad awareness media in 2022, instead of the fall of 2021, which has shifted some of our projections out by a few months, but our market opportunity remains the same. Already we have seen incredible demand for Plenity, and we are confidently on the path to achieve 400% growth in product revenue by the end of the year while significantly improving our gross margin.”

Fiscal Year 2021 Results

A reconciliation of Adjusted EBITDA, a non-GAAP financial measure, to net loss, its most comparable financial measure under generally accepted accounting principles in the United States (“U.S. GAAP”), is included in the tables accompanying this press release.  See “Non-GAAP Financial Measures” for additional important information regarding Adjusted EBITDA.

Recent Business Highlights

Financial Outlook for Fiscal Year 2022

Gelesis provides guidance based on current market conditions and expectations for revenue, gross profit, and Adjusted EBITDA, which is a non-GAAP financial measure.

The guidance provided above constitutes forward-looking statements which are subject to uncertainty.  Actual results may differ materially and we cannot anticipate the effect of changes in marketing investment on our results from operations.  Refer to the “Forward-Looking Statements” safe harbor section below for information on the factors that could cause our actual results to differ materially from these forward-looking statements.

Our product revenue, net, gross profit, and Adjusted EBITDA guidance is based on, among other factors, our current expectations regarding the amount and timing of investments in broad awareness media, which could be impacted by available liquidity and other considerations as we monitor the rate of growth in new Plenity members and units sold during upcoming quarters.

We have not reconciled forward-looking Adjusted EBITDA to its most directly comparable U.S. GAAP measure, net loss, because we cannot predict with reasonable certainty the ultimate outcome of certain components of such reconciliations, including market-related assumptions that are not within our control, or others that may arise, without unreasonable effort. For these reasons, we are unable to assess the probable significance of the unavailable information, which could materially impact the amount of future net loss.

Key Business Metrics

We monitor the following key metrics to help us evaluate our business, identify trends affecting our business, formulate business plans and make strategic decisions. We believe the following metrics are useful in evaluating our business:


Gelesis assumes no obligation and does not intend to update or revise the results provided in this press release. The results provided in this press release represent past performance and are not necessarily predictive of future results.


We define members as the number of consumers in the United States who have begun their weight loss journey with Plenity. This is the cumulative historical number of recurring and non-recurring consumers who have begun their weight loss journey as of the respective reporting date. We do not differentiate from recurring and non-recurring consumers as of the date of this earnings release as (i) we strongly believe every member’s weight-loss journey is chronic and long-term in nature, and (ii) owing to a limited available supply of Plenity to-date, we have not initiated our long-term strategy and mechanisms to retain and/or win-back members.

Units sold

Units sold is defined as the number of 28-day supply units of Plenity sold to consumers based on prescriptions, through our strategic partnerships with online pharmacies and telehealth providers as well as the units sold to our strategic partners outside the United States. Note that the terms “units” and “monthly kits”, as mentioned in Gelesis’ various public disclosures and filings, are synonymous when used to describe the sales volume of Plenity.

Product revenue, net

We recognize product revenue in accordance with Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, when we transfer promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

Our product revenue is derived from product sales of Plenity, net of estimates of variable consideration for which reserves are established for expected product returns, shipping charges to end-users, pharmacy dispensing and platform fees, merchant and processing fees, and promotional discounts offered to end-users.

Average selling price per unit, net

Average selling price per unit, net is the gross price per unit sold during the period net of estimates of per unit variable consideration for which reserves are established for expected product returns, shipping charges to end-users, pharmacy dispensing and platform fees, merchant and processing fees, and promotional discounts offered to end-users.

Gross profit and gross margin

Our gross profit represents product revenue, net, less our total cost of goods sold, and our gross margin is our gross profit expressed as a percentage of our product revenue, net. Our gross profit and gross margin have been and will continue to be affected by a number of factors, including the prices we charge for our product, the costs we incur from our vendors for certain components of our cost of goods sold, the mix of channel sales in a period, and our ability to sell our inventory.

Non-GAAP Financial Measures

In addition to our financial results determined in accordance with GAAP, we believe that Adjusted EBITDA, a non-GAAP measure, is useful in evaluating our operating performance. We define “Adjusted EBITDA” as net (loss) income before depreciation and amortization expenses, provision for (benefit from) income taxes, interest expense, net, stock-based compensation and (gains) and losses related to changes in fair value of our warrant liability, our convertible promissory note liability, our tranche rights liability and the One S.r.l. call option. We use Adjusted EBITDA to evaluate our ongoing operations and for internal planning and forecasting purposes because it facilitates internal comparisons of our historical operating performance. We believe that this non-GAAP financial measure, when taken together with the corresponding GAAP financial measure, net loss, provides meaningful supplemental information regarding our performance by excluding certain items that may not be indicative of our business, results of operations, or outlook. We consider Adjusted EBITDA to be an important measure because it helps illustrate underlying trends in our business and our historical operating performance on a more consistent basis. We believe that Adjusted EBITDA is helpful to our investors as it is a metric used by management in assessing the health of our business and our operating performance.

However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. In addition, other companies, including companies in our industry, may calculate similarly-titled non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of Adjusted EBITDA as a tool for comparison. A reconciliation is provided below for Adjusted EBITDA to the most directly comparable financial measure stated in accordance with GAAP. Investors are encouraged to review the related GAAP financial measure and the reconciliation of this non-GAAP financial measure to its most directly comparable GAAP financial measure, and not to rely on any single financial measure to evaluate our business.
